Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. An amine derivative having a phenanthroimidazole group, the amine derivative being represented by Formula 1, below:
wherein:
Ar 1 , Ar 2 , and Ar 3 are each independently one of a substituent aryl group or a substituent heteroaryl group,
Ar 1 , Ar 2 , and Ar 3 are different substituents from one another, and
at least one of Ar 1 , Ar 2 , or Ar 3 has at least 12 carbon atoms.
2. The amine derivative as claimed in claim 1 , wherein the amine derivative having the phenanthroimidazole group is represented by Formula 2, below:
wherein Ar 1 , Ar 2 , and Ar 3 are as defined with respect to Formula 1.
3. The amine derivative as claimed in claim 1 , wherein Ar 1 , Ar 2 , and Ar 3 are each independently one of a substituent dibenzoheterole group or a substituent aryl group having 6 to 18 carbon atoms.
4. The amine derivative as claimed in claim 1 , wherein Ar 1 , Ar 2 , and Ar 3 are each independently one of a substituent dibenzofuran, a substituent dibenzothiophene, a substituent carbazole, a substituent fluorene, or a substituent phenyl.
5. An organic electroluminescence material comprising an amine derivative having a phenanthroimidazole group as claimed in claim 1 .
6. An electroluminescence device, comprising:
an anode;
a cathode; and
a light-emitting layer and a hole transport layer between the cathode and the anode,
wherein the hole transport layer includes an amine derivative having the phenanthroimidazole group as claimed in claim 1 .
7. An amine derivative having a phenanthroimidazole group, the amine derivative being represented by Formula 1, below:
wherein:
Ar 1 , Ar 2 , and Ar 3 are each independently one of a substituent dibenzofuran, a substituent dibenzothiophene, a substituent carbazole, a substituent fluorene, or a substituent phenyl, and
at least one of Ar 1 , Ar 2 , or Ar 3 has at least 12 carbon atoms.
8. An organic electroluminescence material comprising an amine derivative having a phenanthroimidazole group as claimed in claim 7 .
9. An electroluminescence device, comprising:
an anode;
a cathode; and
a light-emitting layer and a hole transport layer between the cathode and the anode,
wherein the hole transport layer includes an amine derivative having the phenanthroimidazole group as claimed in claim 7 .
10. An amine derivative having a phenanthroimidazole group, the amine derivative including one of the following Compounds 1 to 28:
11. An organic electroluminescence material comprising an amine derivative having a phenanthroimidazole group as claimed in claim 10 .
12. An electroluminescence device, comprising:
an anode;
a cathode; and
a light-emitting layer and a hole transport layer between the cathode and the anode,
wherein the hole transport layer includes an amine derivative having the phenanthroimidazole group as claimed in claim 10 .Cited by (0)
